Yes, in third grade, my winter coat got stuck in the car door as it closed. When my dad started driving away, my tiny little third-grade, 9-year-old body was flung backward and dragged for about two feet before my screaming and other people running in front of the car cause him to stop and realize what had happened. I walked away relatively unscathed, though. Like I said, no broken bones, and I don't even think I bruised too badly. It was a very short distance at a very low spee, but it was terrifying as it was happening.

I probably have gotten more bruises simply by walking into the corners of walls and doors. I'm not very coordinated xD I actually do trip over flat surfaces, haha.
